4th grade place value

UI – Students have a general idea of place value from 3rd grade, but do not know how many times greater when moving from one place to the place at the left (ones place to tens place)

CI – Aware that there is a pattern when changing from one place to the next place.

CC – Aware that the pattern is times 10

UC – Able to move from one place to another such as ones place, to tens place, to hundreds place by multiplying by 10. Or ones place to hundreds place

CC – Develop the idea that when moving from a larger place to a smaller place you divide by 10.
